Okay ima girl and the other day i had unprotected sex and he didn't cum or anything culd i be pregnant?

Yes: Unprotected intercourse can result in pregnancy, even if your partner did not ejaculate. This is because sperm cells can be found in the "pre-cum", a small amount of semen that is secreted prior to ejaculation.

Possible: Well certainly you could, that's what unprotected sex means. No one can tell you how likely it is, trying to guess is just that: guessing. Assuming you do not want to get pregnant, do yourselves a big favor and either don't have sex or use reliable protection. After unprotected sex you can talk about it 24/7 but you can't know until a period or when you can do a reliable test!
